* | | net/iproute2.sh: in _get_mac_address, don't return multiple addressesPatrick McLean2021-03-301-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if a device has virtual functions configured, ip will list the mac addresses for the virtual functions on a device as well as the device itself. This makes _get_mac_address return these addresses as well, causing functions that consume this output to fail in "interesting" ways. This makes sure it only returns 1 address. Also don't set the mac variable to the address of the interface from sysfs, then proceed to overwrite it with a call to "ip". Signed-off-by: Patrick McLean <chutzpah@gentoo.org>

* | net/iproute2.sh: Add initial support for network namespacesPatrick McLean2021-03-113-47/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for network namespaces. An interface can be assigned to a network namespace with `netns_${IFACE}`. The script will move the interface to the namespace if it is not already there. This adds a helper functions to `functions.sh` called `_netns`, this function facilitates scripts working withing network namespaces. It allows eching to sysfs etc files, globbing, and arbitrary commands within a network namespace. This uses a wrapper for the `ip` command so all calls to it will add `-n ${netns}` so it's operating in the netns. Basic interface configuration is tested and working.

* | net/apipa.sh: Simplify and address the remaining portability issuesKerin Millar2021-02-021-34/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-factor the over-generalised seeding function into a _random_uint16 function. Have it use a simpler, faster method to collect entropy, with the aid of od(1). Shorten the previously rambling comment. Simplify the _random_apipa_octets function. Clamp the seed to the range 0-32767 for maximal portability. Convey the seed as a formal parameter, rather then inject it. Use a simpler method to produce the octets, running awk(1) only once. Format the random float, so that awk(1) is prevented from using scientific notation to represent certain numbers. Change a variable name in the subshell responsible for reading the list of octet pairs, so as to be less confusing to future readers. Note that the portability issue mentioned by commit 31a05f1 is addressed. The code should now be fully POSIX-compliant, save for the continued use of the local keyword, upon which it does not rely.

* | net/apipa.sh: Account for the first and last /24 being reservedKerin Millar2021-01-271-3/+3
| | | | | | | | | | | | | | | | | | | | While the 169.254/16 prefix is used to define IPv4 link-local addresses, RFC 3927 states that the first 256 and last 256 addresses are reserved for future use. Therefore, the number of available addresses amounts to neither 64516 nor 65534, but actually 65024.

* | net/apipa.sh: fix broken implementation by way of a rewriteKerin Millar2021-01-271-27/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sadly, the present implementation has never functioned correctly. The original author employed incorrect syntax for what was intended to be a command substitution. As a result, the _random() function is never called. What actually happens is that arping is needlessly executed exactly 64516 times, with no address ever being considered as a valid candidate. Furthermore, this module has other bugs and is poorly designed. Here are the reasons as to why:- • the 169.254.0.0/16 block offers 65534 addresses, not 64516 • the main loop is horrendously slow at enumerating the address block • it counts to 64516 but doesn't ensure that each address is unique! • it prefers bash for generating entropy (fine, but non-standard) • it falls back to a non-standard utility for generating entropy Therefore, I decided to re-write most of it. The fundamental difference is that all 65534 octet pairs are generated up front before being processed by the main loop. At most, every possible address will now be tested exactly once. In fact, this approach turns out to be faster by an order of magnitude. The following synthetic tests - which calculate the time taken to enumerate the entire address space - demonstrate the tremendous difference between the existing code and mine. Of course, to ensure that the comparison was meaningful, I rectified the command substitution bug in the existing code. # time bash apipa-old-test.sh real 2m34.367s user 1m9.959s sys 1m37.502s # time bash apipa-new-test.sh real 0m1.119s user 0m0.965s sys 0m0.182s Note that the new _random_apipa_octets() function is responsible for generating all 65534 combinations of octet pairs in a random order. It mainly relies on awk(1) and sort(1). Where possible, a seed is obtained from /dev/urandom for the benefit of awk's RNG, but this is not required. I have isolated and tested the new functions on GNU/Linux, macOS, FreeBSD, NetBSD, OpenBSD and MirBSD. I have individually tested gawk, mawk, nawk, busybox awk and the awk implementations provided by the previously mentioned operating systems in the case that they are distinct. The only incompatiblity that I was personally able to find was with the awk implementation of MirBSD, which affects the final invocation of awk in the _random_apipa_octets function. However, MirBSD was forked from an old version of OpenBSD and seems sufficiently obscure so as not to be worth worrying about. If someone should try to integrate netifrc into MirBSD one day then the matter can be dealt with then. Finally, I want to thank Steve Arnold for bringing the original bug to my attention. Congratulations, Steve. You may be the only known user of net/apipa.sh on the planet.

* | Use sysfs to obtain the MAC address in net/iproute2.shKerin Millar2021-01-241-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | Dispense with the hideous ip-link(8) parser. Instead, collect the MAC address by reading from the relevant sysfs file. While at it, tidy up the remainder of the function so that the control flow is easier to ascertain at a glance. Note that the address will be rendered in upper case, just as it was before.

* | dhclientv6: Add DHCPv6 support via dhclientDaniel Solano Gómez2020-06-026-6/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds DHCPv6 support to OpenRC in Linux using dhclient as outlined by Stuart Longland at <http://stuartl.longlandclan.yi.org/blog/2011/02/15/gentoo-and-dhcpv6/>. The main place where the new support is added is via a modified copy of the dhclient.sh script that: - Renames functions using a 'v6' suffix - Uses a different pid file - Uses the '-6' argument when invoking dhclient - Recognizes new DHCPv6-specific configuration variables with a fallback to the DHCP configuration variables. Additionally: 1. The iproute2 and Linux ifconfig scripts have been ammended to be able to return IPv6 addresses using new '_get_inet6_address' and '_get_inet6_addresses' functions. 2. The 'net.lo' init script now has a '_show_address6' function. 3. The documentation in the Linux net.example now contains some DHCPv6 information. Reported-by: Dustin C.
